improvements in freight car door locks and Y has for an object toprovide a lock that will securely. hold and lock the door in its closedposition and preventY any lateral or transverse movement as well asshifting', both of which movements are common in freight car vdoors withthe form of locks now generallyv 1n use.

Another object of the present invention is to provide a freight'car doorlock .that does away withthe hasps on the front of the door or on theframe of the .s car adjacent the front edge of the door and to provide alock that ispreferably.positioned yat the lower right hand corner'of thedoor. i

ln the locks now generally employed, the hasp is often torn .from a dooror the frame adjacent the front edge ofthe door and the wood workbecomes damagedor torn out as the continued jarring and shifting of theVdoor will tear the haspv or latch from its set position. Y

Another object of my invention 'therefore `is to provide a lock whereinvthere isyno strain whatever. on the latchor on the hasp, the strainfalling on an arm that is especially provided and of sufcient size. andthickness towithstand the strain that will be placed upon it andthustightly hold the'door in its closed and locked position. Y j vStillvanother object of the present invention is to provide a lock that.is preferably situated at the4 lower right hand vcorner of the door thusdoing away with the usual hasp. at the front ofthe door and at the sametime due to its position and construction will prevent the-door frombeing surreptitiously forced slightly upwardly and then transversely -tothe Vcar without breaking the seal of the lock, which is possible `withthe locks now in general use. Y Y

Still another objectofmy invention is to prov-idea lock consisting of anarm that is adapted to be swung into a cut-out portion Y or a ,pocketwhich fis formed in the lower sill of the door, which arm is of greatover ,ai hasp to lock the door,

strength and when wthinthe-pocket will prevent any shifting of the doorandi will also prevent the door from being moved transversely lofthecar.. ,Also a latch'w'ill be secured to this arm which will be placed`andthe strains thus falling on the` aforesaid arm and fsill withthepocket therein rather thang-on [the ha'p 'or latch.'

till another object lof the invention is -to providey a ylock forfreight,V car doors coniprising two plates .one ofwhich is prefer# ablysecured to the lo-werrighthand corrieri i of the door and on whiehplateis secured Qa conventional hasp and latch member formed in thelowerportion of the vv plate pocket frame ,which yfits within a .pocketformed within the lower V,sill of ,the door. The second plate isprovided `'with ard to Vwhich is4 pivotally secured an arm Y Y ina steelv a standadapted :to fit within said pocket and to lthe lower end ofsaid arm Y A pass over the hasp above mentioned.

Still another object jof the invention-.is to provide a f reightcar`door lock which may be quickly and rapidly applied to .the freight car`doors now in v.use witheut i-n any "wgay changing the character of thedoor and with onlya minimum` amount? of labor, and; to provide a vlockwhich .maybe quickly and:

s secured a latch to door against :any transverse o r lateral niove.-v iment asv well as longitudinal movement. l'

*With these Vand numerous other objectsyin 90 Y view my invention...relates tocer'tain'fnew and novel arrangements-v :and comloinationfjof partsas will be hereinafter scribed and pointed vout intheclaims.

jReferri-ngnowto thedrawings: .Y

i, on line 7 7 of Fig. 4, the dotted lines showin the arm in severalpositions.

Fig-8 is a perspective of the upper plate of the lock, before'the hasphas been applied. v y

In the drawings, a portion 1 of a freight car is shown having the usualroller track 2 on which are shown the hangers 8 which support the door4, while at the bottom of the door are shown the conventional guidebrackets 5. All of the parts above enumerated are of conventional designand it will be understood that my lock, shortly to be described, may beattached to any freight car door or in fact to any sliding door.

In Fig. 1 the ordinary locking means and hasp have been removed from thedoor and a small strip 6 is shown fastened over the place where theformer latchv was situated.

It is to be understood that my lock may be quickly and readily fastenedto the doors now in use with but little effort, necessitating thecutting of only one pocket in the lower corner of the door, or the lockmay be applied to the new doors when the car is constructed.

' Referring now more in detail to my invention and the enlarged views,Figs. 2, 8, 4 and 8 there is shown a plate 7 that is secured to thelower right hand corner of the door, this plate having a fla-ngeside'member 8 which may be'serewed or otherwise fastened to the edge ofthe door, the plate is also fastened at itsupper left hand corner bya'screw or rivet 9.` This plate 7 is also slightly offset throughout itslength at 10 so that a strip of ymetal 11 may be placed beneath theoffset portion 12 which strip 11 is bent about midwayr of its length toformv the pocket walls 13, and then extends parallel with the plate 7and thenis flanged as at 14 to lit snugly around the edge of the doorand to be fastened to the door on its inner side.

The offset portion 12 of the plate 7 is also cut as at 15,'the edgesbent downwardly to lie along the side walls 18 of the pocket.

Before applying this plate 7 and its component strip 11, a pocket 17 iscut into the lower edge ofthe door so that the pocket walls k3 maysnugly fit therein. After this plate has been fastened, rivets or bolts18 will be passed throughV the strip 11 and through the plate 7 tosecurely lfasten these two parts tothe door. 1 y

Angularly secured by rivets to this plate 7 is a hasp and bolt member 19which is a conlventional one, it being positioned however',

angularly rather than vertical as in most instances.

Referring now to the other member of the lock, that is, that part whichis -fastened tothe frame of the ear below the door, it will be seen thatthis likewiseconsists of'a plate or strip 2O (see F ig. 5) which isflanged at one end as at 2l which flange is driven into the wood, or thewood is first cut out for the reception of this end; this plate beingsecured by the numerous bolts 22 which pass entirely through theframework of the car. A strong upright or standard 23 is shown which ispreferably formed integral with the plate 20 and extends downwardly forsome distance below the plate, and to which standard is pivotallysecured the relatively thick arin 24, this arm being designed to snuglylit within the reinforced pocket 17. 'lhis arm lies fiat against theupright when in its uppermost position, the upright being nearly as longas the arm, thus a supporting wall for the arm to hold it againstlateral movenient in the rearward direction.

` At the lower end of this arm, that is when the arm is in a position asshown in Fig. 3, there is placed an eye 25 which has been previouslypassed through the latch 26,

this eye 25 being pressed or welded in the arm 24. The latch 26 isprovided with a small cnt out portion 27 which is passed over the haspon the member 19 when the arm 24 has been swung upwardly into thereinforced pocketv 17. One of the guidebrackets 5, heretofore mentioned,is riveted over the far end of the plate 2O which is clearly shown inthe several figures.

After the latch member 26 has been passedl over the hasp, theconventional locking bolt 28 on the hasp member 19 will be passedthrough the hasp and the conventional seal 29 passed through the slot 30in the locking bolt 28.

The operation of the lock is extremely simpleand a short descriptiononly is necessary.

To lock the door, the door will be simplyv moved to its closed positionasV shown in Fig. 3, the arm 24 then'registering with the pocket will beswung upwardly into the pocket 17, it abutting against the metal edges16 and the rear wall of the pocket 13 formed in the plate 11, and thelatch then placed over the hasp of the member 19 and the bolt 28 shotinto place.

' Of course, in unlocking the door, the operation is simply reversedwhen the door may be swung to its open position.

The many advantages of a lock of this kind will be readily apparent, thechief of which is that the arm 24 fitting snugly within the pocketprevents any longitudinal shifting of the door, and the strain, ofcourse, falling on the relatively thick arm 24 Y pocket; these aereas@and on the metal parts of the reinforced parts being especiallydesignt-'d to withstand the strains and therefore not likely to bebroken yor torn from their position which is so often the case with thelocks now inuse.

' Furthermore not only is the door heldfrom longitudinally shifting butby swingingthe arm into its pocket andthen placing the latch'over thehasp the door `is held against any lateral movement. Y v l' Of coursethe bracket guides are'designed to hold the door against lateralmovement,

but it is well known that robbers or people unauthorized to open thedoors will someengaged from the guide brackets and even` were thispossible, it could not swing later- Y ally enough to give admission tothe car.-

From the foregoing it will be seen that I have provided a lock whereinall ofthe strain falls on an arm that is especially provided for thispurpose and wherein none of tlie strain is placed on the latch or hasp,so that although I use a `hasp and latch member I do not subject themtothe strain that usually falls upon them. Y

Furthermore I have provided a lock tha is extremely strong and is to beplaced preferably, down in the right hand lowercorner which will preventthe. door from being moved laterally by unauthorized persons and preventunauthorized entrance to the car: and furthermore, the lock will holdthe door steadily in position and prevent it from shiftinglongitudinally or laterally while the car is in motion` Y v Also I haveprovided a lock that maybe quickly applied to the doors now in use withbut little effort and little expense or may be readily applied to carsunder construction.

Many slight changes may be made in the plates or arms and latch memberswithout departing in 'any way from the spirit and scope of my invention.
